Acute hemorrhagic leukoencephalitis. A successful recovery

|October 1, 1991
Summary
A woman developed acute hemorrhagic leukoencephalitis after a respiratory infection. Prompt treatment involving intracranial pressure reduction and immunosuppression led to a full recovery without lasting effects.
Area of Science:
- Neurology
- Infectious Diseases
- Immunology
Background:
- Acute hemorrhagic leukoencephalitis (AHLE) is a rare, severe neurological disorder.
- AHLE can be triggered by infections, though its exact pathogenesis remains unclear.
- Mycoplasmal pneumonia is a potential, albeit unproven, trigger in this case.
Observation:
- A 50-year-old female presented with symptoms of AHLE 7 days post-respiratory infection.
- Clinical and laboratory findings suggested Mycoplasmal pneumonia, including positive Coomb's test and cold agglutinins.
- Brain biopsy confirmed acute hemorrhagic leukoencephalitis.
Findings:
- The patient's AHLE was successfully managed with a multi-faceted treatment approach.
- Intracranial pressure was reduced using mannitol, hyperventilation, and phenobarbital.
- Prolonged immunosuppression involved plasmapheresis, steroids, and cyclophosphamide.
Implications:
- This case highlights the potential link between respiratory infections and AHLE.
- Aggressive management combining ICP control and immunosuppression can lead to favorable outcomes in AHLE.
- Early diagnosis and intervention are crucial for preventing long-term neurological sequelae.
